Engineered for superior off-road performance during dynamic movement, the Alpinestars Supertech RK-10 PLASMA Knee Brace offers the highest level of knee support. This brace is ultra-lightweight, breathable, comfortable, and protective. It features a free-floating Nucleon PLASMA knee protector encased in an innovative asymmetric forged carbon fiber frame construction for maximum rigidity and weight-saving. The brace comes as a pair. Designed with input from professional MX riders, the 34-ply carbon fiber frame balances flex and stiffness for rider comfort and support, reducing the risk of injuries to ligaments and meniscus. The frame geometry is optimized through 3D scans of athletes for ideal internal volume and precise hinge width. The frame's extremities have a soft, flexible construction with smooth transitions to prevent direct contact between hard carbon fiber edges and the skin.
